23/08/2011 12:42 +0100 – Ngog has yet to feature for the Reds this season after being an unused substitute against Sunderland on the opening day and not making the squad for Saturday's win at Arsenal. Manchester City defender Boyata, meanwhile, is on the periphery in Roberto Mancini's squad and has previously been linked with Bristol City. Boyata's father claimed back in June that the youngster would not be keen to join Bolton, but reports have claimed the Trotters have been given permission to speak to the Belgium international. Coyle is also chasing Boyata's team-mate Shaun Wright-Phillips, but the Bolton boss is reluctant to confirm which players he is trying to bring to the Reebok Stadium. "I am interested in a lot of players," said Coyle. "Until I have got everything cut and dried, I am loath to mention individuals. "There are bigger clubs than Bolton out there who could come and steal your thunder. "Those two are both very good players. Whether we are able to bring them to the club, time will tell."
